Not yet, I did try 2.4.19, to see if that worked better, but got the
same crash. 2.4.18 seems to be different, however, since it does not
autodetect the drives (and does not crash when I pass the IDE addresses
manually).

No errors were reported.

Someone decoded it and posted a decoded trace. Did that not arrive to
the list properly?

I'd prefer to use the on-board RAID to be compatible with other OSes.
And, according to people I have asked, the Linux software-RAID is not
very reliable either, so I don't feel especially inclined to switch.

If I run this (I can boot the machine using 2.4.18), what should I
look for? I haven't debugged the kernel before, it has just always
worked for me, on all the machines I've tried it. I've only ever had
the kernel crash once on me before since 1996.

That might be a typo on my part.

> there are no printk's before the oops?

The last thing that happens before the crash is that it tries to
enumerate the hard disk partitions. I lists a few but then crashes.
